UniProtKB - A0A4W2EAC1 (A0A4W2EAC1_BOBOX)
Protein
Inosine triphosphate pyrophosphatase
Gene
ITPA
Organism
Bos indicus x Bos taurus (Hybrid cattle)
Status
Functioni
Pyrophosphatase that hydrolyzes the non-canonical purine nucleotides inosine triphosphate (ITP), deoxyinosine triphosphate (dITP) as well as 2'-deoxy-N-6-hydroxylaminopurine triposphate (dHAPTP) and xanthosine 5'-triphosphate (XTP) to their respective monophosphate derivatives. The enzyme does not distinguish between the deoxy- and ribose forms. Probably excludes non-canonical purines from RNA and DNA precursor pools, thus preventing their incorporation into RNA and DNA and avoiding chromosomal lesions.UniRule annotation
